Detailed Description

NanoCanvas represents objects for drawing in memory buffer

Deprecated:

Use NanoCanvas1, NanoCanvas8, NanoCanvas16 instead

Definition at line 39 of file nano_gfx.h.

Constructor & Destructor Documentation

NanoCanvas()

NanoCanvas::NanoCanvas ( uint8_t  w, uint8_t  h, uint8_t *  bytes  )

Creates new canvas object. Width can be of any value. Height should be divided by 8. Memory buffer must be not less than w * h / 8.

Parameters

w	- width
h	- height
bytes	- pointer to memory buffer to use
